Table top ovens you can set to cook in advance???

[partyatthepalace]

Do these exist???

I’d like one I can put food in when I leave for work, set to turn on at a particular time so the food is cooked when I get home.

I feel like they must exist but am finding such a thing hard to track down (ideally an oven/microwave combi)

Would a timer plug do the trick?

Might be for safety reasons that they don't exist?
